Sp= ace is only preserved if the element has some other text content rather tha= n exclusively whitespace. This was obviously implemented this way to not ch= ange behavior and break existing code. This is of course still a problem. > xml:space=3D"preserve" does not handle blank strings properly > ----------------------------------------------------------- > > Key: CONFIGURATION-703 > URL: https://issues.apache.org/jira/browse/CONFIGURATION-= 703 > Project: Commons Configuration > Issue Type: Bug > Affects Versions: 2.2 > Reporter: Pascal Essiembre > Priority: Major > > When using XMLConfiguration 2, tags containing only white spaces are not = handled properly when xml:space=3D"preserve" is set.=C2=A0 'null' is return= ed instead of the actual spaces.=C2=A0 To reproduce: > =C2=A0 > {code:java} > XMLConfiguration xml =3D new BasicConfigurationBuilder<>( > XMLConfiguration.class).configure( > new Parameters().xml()).getConfiguration(); > FileHandler fh =3D new FileHandler(xml); > fh.load(new StringReader(" ")); > System.out.println("TEST: '" + xml.getString("") + "'"); > // Outputs -> TEST: 'null' > // Should be -> TEST: ' ' > {code} > =C2=A0 > =C2=A0 > =C2=A0 > =C2=A0 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
